Reference SBGH311 commemorates the 25th anniversary of the first Caliber 9S while also honoring the distinct beauty of Shizukuishi.
Introducing a new pattern for Grand Seiko, the dial of SBGH311 evokes the sea of clouds that cover Mt. Iwate at daybreak. This mesmerizing phenomenon occurs when the air is so humid and still that dense clouds overlap and create a silvery-white sea. The contours of these clouds are expressed on the dial, which is made possible through electroforming. The diamond-cut hour and minute hands, tempered seconds hand, and multi-faceted indexes stand out against the dial's intricate texture, ensuring legibility at a glance.
The stainless steel case measures 37mm in diameter and 13.3mm in thickness, and it is paired with a stainless steel bracelet with a three-fold clasp. The smaller case size is a nod to the original watches that debuted the first 9S movement back in 1998.
At the heart of SBGH311 is the Hi-Beat 36000 automatic mechanical Caliber 9S85. This exceptional movement is hand-assembled at Grand Seiko Studio Shizukuishi, the center of Grand Seiko's mechanical watchmaking. It features an accuracy rating of +5 / -3 seconds per day with a 55-hour power reserve. Additionally, the titanium oscillating weight has undergone an anodic oxidation treatment, which gives it an eye-catching blue hue.
SBGH311 is a limited edition of 1,200 pieces.
